Hi all. I'm covering a large section of old hardwood flooring in my 1960s house with carpet soon (kids and dogs need something softer to run around on). Beforehand though, I really want to take care of some of the nasty squeaks in the floor. Naturally, they're prominant in the areas that are walked on most, near doorways and at the foot of the stairs. Very annoying. I know if I run a bunch of screws into the joists that will probably stop much of it, but the last thing I want to do is destroy the floor...so... Can I do anything from the basement? I've heard stories of baby powder helping...but can that really be a permanent fix?? Suggestions on how to get rid of these squeaks will really help guys! Thanks.
